  • Uncontrolled hypertension, defined by a systolic blood pressure (SBP) ≥160 mmHg and/or diastolic blood pressure (DBP) ≥100 mmHg, with or without antihypertensive medication. Initiation or adjustment of antihypertensive medication(s) is allowed prior to screening
  • Long QT syndrome, family history of idiopathic sudden death or congenital long QT syndrome or any of the following: risk factors for torsades de pointe including uncorrected hypokalemia or hypomagnesemia, history of cardiac failure or history of clinically significant/symptomatic bradycardia; concomitant medications with a known risk to prolong the QT interval and known to cause torsades de pointe that cannot be discontinued or replaced by safe alternative medications.
  • Bradycardia (heart rate less than 50 at rest), by electrocardiogram (ECG) or pulse.
  • Inability to determine the QT interval on the ECG (i.e., unreadable or not interpretable) or corrected QT (QTcF) >450 msec for males and >470 msec for females (using Fridericia's correction) during Screening, based on the mean of triplicate ECGs
• Currently receiving any of the following medications and cannot be discontinued 7 days prior to the start of the treatment: Medications with a known risk to prolong the QT interval or induce Torsade de Pointes (TdP). CredibleMeds list of drugs known to cause TdP may be used as a reference for this study to determine which drugs are prohibited using the following link: https://crediblemeds.org/new-drug-list or a crediblemeds mobile application.
  • °Herbal preparations/medications, with the exception of cannabinoids, CBD compounds, etc.
